What is the FIRST sign of the existence of a well-developed tropical cyclone?

🔍 Key Concepts

• Tropical cyclone structure and size – how far effects are felt from the center • Ocean swell vs. local wind waves – which one can travel long distances from the storm • The difference between early distant signs and weather that occurs only when the storm is nearby

💭 Think About

• Ask yourself: which choice could be detected hundreds of miles away from the cyclone, before any bad weather arrives? • Which option describes a sea state that is NOT consistent with the local light winds you might be experiencing? • Which sign would appear first, well before thunderstorms, strong winds, or rapid pressure falls occur?

✅ Before You Answer

• Compare swell direction versus local wind direction – could they be different? • Decide which options are mainly local weather effects (close to the storm) versus remote effects (far from the storm). • Make sure the sign you choose could be noticed by a vessel at sea long before the main storm field arrives.
